The Milwaukee 2456-20 is a 12-volt cordless impact wrench built on the M12 battery platform. It weighs about 1.5 lb, has multiple speed gears and an LED light, and uses a brushed motor rather than brushless. It suits light fastening and small-bolt work where a compact, one-handed tool matters more than raw torque. Against 18-volt impact wrenches it gives up power, and against brushless M12 models it gives up runtime and motor life, but it is smaller and simpler.
